Biogeochemical cycles (40)-extended time

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. It is essential for life as it is a key component of amino acids, proteins, and nucleic acids.

Front

What are the main processes involved in the carbon cycle?

Back

The main processes include photosynthesis, respiration, decomposition, and combustion. These processes cycle carbon through the atmosphere, biosphere, and geosphere.

What is transpiration?

Back

Transpiration is the process by which water vapor is released into the atmosphere from the leaves of plants.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.

How do human activities affect the nitrogen cycle?

Back

Human activities, such as agriculture and the use of fertilizers, can lead to excess nitrogen entering water bodies, causing pollution and eutrophication.

What role do decomposers play in biogeochemical cycles?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for plants.

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis allows plants to absorb carbon dioxide from the atmosphere and convert it into organic matter, releasing oxygen as a byproduct.

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.
